Do I need to flush or transplant? I went the past two days without watering and the soil is just now starting to dry, atleast on the top.
Flushing is unlikely going to cure your woes. I believe your issue is the time released neuts in the miracle grow soil. They won't break down with water at an equal rate. Myself would transplant. I also would stay away form all potting soils and go with something nutrient devoid. Do a bit more research I'm sure there is a garden center near you. If your only finding MG. I suggest expanding your search to more than just wallmart
